New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 3.4
SynopsisThe remote name server is affected by a denial of service vulnerability.
DescriptionAccording to its self-reported version number, the remote Unbound DNS resolver is affected by a denial of service vulnerability due to a failure to send responses for signed zones after mishandling an unspecified query. An attacker can exploit this, via a crafted query, to cause a DNSSEC outage, resulting in a denial of service condition.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
SolutionUpgrade to Unbound version 1.4.4 or later.
